Trainer Hughie Morrison fights to clear his name after positive drug test

Morrison - who could lose his licence for anything between a year and 10 years if found guilty - fiercely denies any wrongdoing.

Trainer Hughie Morrison has been charged with breaching the rules of racing after his horse Our Little Sister tested positive for banned substance nandrolone following a race at Wolverhampton in January, the British Horseracing Authority has confirmed.

The BHA said that, in accordance with its normal practice of assisting a trainer in circumstances such as these to establish the source of the administration, it has "carried out all reasonable inquiries it can with the full co-operation of Mr Morrison".
